TimeSource 3550

Overview

Stratum 1 Performance in GPS Hostile Environments

The newly-introduced TimeSource® 3550 is a standalone Primary Reference Source (PRS) which provides Stratum 1 performance in GPS hostile environments via external wall mount or roof mounts. Its new highly integrated rubidium oscillator maintains extended holdover spec with reduced footprint. TimeSource 3550 consists of single unit modules that plug into a rack-mounted shelf. It operates with an external high precision GPS timing antenna to meet GR-2830 and EN 300 462-6-1 requirements, and comes with two output ports that are software configurable for T1, E1, 2.048 MHz or composite clock to support frequency timing applications. There is also a SW License option for 8 additional outputs. Two shelves are available: ANSI standard with rear connectors and ETSI standard with front facing connector access. The TimeSource 3050 modules may be used in previously supplied shelves of TimeSource 3000 and 3100 products.

Improved GPS antenna design

The new GPS antennas for the TimeSource 3550 provide advanced narrowband filtering to protect against interference from adjacent spectrum. They also provide automatic compensation for cable delay via TWTT (Two-Way Time Transfer). The GPS antenna can be installed up to 1,000 feet from the office shelf, without amplifiers, using inexpensive thin coax cable.
